SIPHON Filed March 25. 1929 INVENTOR ATTOR NEY Patented May 6, 1930 UNITED STATES ERASTUS B. MITCHELL, F BLAGKFOO'I, IDAHO srrnon Application filed March 25, 1929. Serial No. 349,776.

This invention relates to improvements in siphons and has for an object the provision ot a siphon which may be used for irrigating purposes, and which will not wash out 6 the ground and may be used upon any side of a ditch.

An important object of the invention is the provision of asiphon which will not wash out the land and from which water may 1 flow in opposite directions, or may be controlled so as to flow in one direction.

With the above and other objects in View, the invention further includes the following novel features and details of construction, to

be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawing Figure 1 is a sectional View illustrating the invention.

Figure 2 is an enlarged fragmentary section of the lower end of the siphon.

Figure 3 is an end view of the subject matter of Figure 2.

Referring to the drawing in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates the short leg 01 the siphon, 11 the long leg and 12 a section which connects the short and long legs so that a conduit is pro vided which may be of any suitable diameter and length.

The short leg of the siphon is designed to be placed within the ditch to be drained, and

the long leg arranged upon the opposite side of the ditch so that when flow is started through the siphon, the water within the ditch will flow outward as will be readily understood.

Located at the outer end of the long leg 11 is a pipe 13 which communicates with the leg 11 intermediate the ends of the pipe. The opposite ends of the pipe 11 are open and these open ends are controlled by gate valves 14. v

A neck 15 extends from the upper end of the leg 11 and may be closed by a cap 16.

In the use of the invention, the siphon is arranged as shown in Figure 1 with the gate 59 valves 14c closed. The cap 16 is removed from the filling neck 15 so that the leg llmay be filled with water, after which the cap 16 is replaced. The gates 14: are then opened so that water within the leg 11 will iiow outward and create a suction through the leg 10 and the connection 12.

The valves 14: may be adjusted to regulate he rate of flow through the siphon and as he pipe 13 is horizontally arranged, water will flow outward upon the ground Without endency to wash out the ground. In addi- 'on, if desired, one of the gates 14 may be c osed so that the direction of flow of the water may be controlled. It is preferred however to open both of the gates so as to reduce the force of the water.

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is here in reservedto make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is:

A siphon for irrigating land comprising a short leg and a vertically inclined downwardly extending long leg, a horizontal pipe extending transversely of and secured to the outer extremity of the long leg and having communication therewith, one wall of the pipe being opposed to the extreme open end of the long leg, and valves within the pipe beyond the end of the long leg.

In testimony whereof I afiiX my signature.
